A first-time mother who was struggling to produce enough breast milk to feed her newborn was advised to eat cookies that contained extra galactagogues (i.e., ingredients that increase milk flow). The functional cookies worked, but weren’t particularly palatable, and that gave Jennifer Acuna a business idea. Several years later, the business she launched has been successful enough to move from her kitchen table near Harrisburg, Pa., to a 2,400 square-foot bakery. Lactation cookies, brownies, and granola laced with galactagogues have become serious business. Buy Buy Baby and Babies 'R' Us sell bake-at-home mixes. Common galactagogues include oats, flax meal, fenugreek, and brewer's yeast.
